Can I edit documents directly on the network with Android?

While editing and saving documents on a network with Word in windows the entire process takes places where the document is located and the file is not transferred to the device. However while attempting this on android, the file seems to be copied into the android device and the changes made are limited to the downloaded file in the device. This file is then required to be separately uploaded to the network which causes too many copies of the file floating around. Is there a workaround for this i.e. can a document be edited in an android device without copying the document to the device?
